* Fixed chmodding to use the correct path to the directory. This fixes
file permissions in rpm's converted to other formats, a bug introduced
at 7.0.
* Fixed some undefined value warnings (which pointed out real but rare
bugs).
* Fixed a rare, but bad little bug. If you ran alien in a directory that
had the suid/sgid bit set (as my home directory does), and generated
debs and probably other formats, it generated packages with the root
directory suid/sgid.
